SILO AND BUILDING-TILES THEREFOR.

Application filed November 15, 1912.

To all whom it may concern:

Be it known that I, EDWIN BABB, a resident of Akron, in the county ofSummit and State of Ohio, have invented a new and useful Improvement inSilos and Building- Tiles Therefor, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, 111 which Figure 1 is aside elevation of a portion of a silo built in accordance with my invention. Fig. 2 is a sectional view on the line IIII of Fig. 1. Fig. 3 isan enlarged sectional view similar to Fig. 2, of a portion of the silo.Fig. d is a plan view of a portion of one course or row ofthehorizontally extending tiles with the concrete. removed. Fig. 5 is adetail sectional view on the line V-V of Fig. 41-. Fig. 6 is a sectionalview on the line VIVI of Fig. 3; and Fig. 7 is a detail sectional viewthrough a portion of two doors showing a modified form of junctionbetween adjacent doors.

My invention relates to silos and build ing tiles for use in theconstruction thereof, and is designed to provide a tile which can becheaply manufactured and which is provided with means for receivingreinforcing rods to prevent the spreading of the tiles due to theinternal pressure caused by the weight of the silage.

My improved tile also provides means by which silos may be rapidly andcheaply constructed, does away with the use of expensive connectingdevices, and provides connecting means which reinforce the silo and atthe same time retains the tiles in their proper position.

The precise nature of my invention will be best understood by referenceto the accompanying drawings, which will now be described, it beingpremised, however, that various changes may be made in the details ofconstruction and general arrangement of the parts, without departingfrom the spirit and scope of my invention, as defined in the appendedclaims.

Referring to the accompanying drawings, the numeral 2 designates thetiles from which the body of the silo is composed, while 3 and 1designate the end or door tiles placed at the ends of each row of'tiles2. Each tile 3 is equal in length to one of the tiles 2, while each tile4 is only one- Specification of Letters Patent.

half the length of a tile 3, as can be seen by reference to Fig. 1 ofthe drawings.

7 Each tile 2 is closed at the top, bottom and sides, and has aplurality of l0ngitudinal openings therethrough, subdivided bypartitions 5 and 6. Each of these has a deep longitudinal recess 7 inits upper surface, the lateral walls of which, as well as the uppersurface of the tile at each side of the recess 7, are formed withgrooves 8. Each tile also has a plurality of longitudinal grooves 9in'its bottom face. The tiles 3 and 4: are each provided with verticallyextending recesses, divided by partitions 10, the ends and sides ofthese tiles being closed. The top of each of the tiles 3 and 1 isprovided with grooves or recesses 11 which form continuations of thegrooves 7 in the tiles 2.

After the foundation has been laid, a circular row of the tiles 2 isfirst laid. A cast iron plate, such as indicated at 12 in Figs. 1 and 3is then laid on the top of the first course at the point where theopening in the silo is to be formed. The end tiles, such as 3 or 4, arethen placed on each side of the plate, and the row is completed byplacing the tiles 2 in position. After the first row has been laid, astrip of reinforcing material is laid in the recess 7 in the top of thiscourse, the ends of which strip are connected to I-bars 13. These barsare provided with eyes for the reception of a connecting member 11 tosecure the ends of the reinforce to each other. The space is then filledwith concrete or cement and, a small portion of cement is placed on thetop of the second course of tiles. The third course is then started byplacing end tiles, such as 4-, above the tiles 3, which are one-half thelength of the tiles 3. The course is then completed by laying the tiles2; and after this course has been laid, a second reinforcing strip islaid in the groove in the tops of the tiles, the ends of this strip areconnected to each other by a bar 15, whose ends are shaped in. the samemanner as the inner ends of the eye-bars 13, which extends across thedoor-way. This operation is repeated until the proper number of courseshave been laid to complete the silo.

Each of the end tiles is recessed as indi cated at 16, to receive doors17, which are held in position by means of the material within the siloand 17 are packing members between the doors and the walls of therecesses 16. The upper face of the door plate 12 is flanged, asindicated at 18, while the lower face of the door 17 is shaped to fitthe flange, to exclude all moisture from the outside, and to prevent anyof the moisture from the silage to pass outwardly through said joint.The joints between adj acent doors may be made by a plain tongue orgroove joint, as indicated in Fig. 6, or the tops and bottoms of thedoors may be shaped as indicated in Fig. 7.

In the drawings, I have shown the connecting rods 14 between the ends ofthe reinforcing rods connected to I-members 13 which, in turn, areconnected at 13 to the ends of the reinforcing elements, while the rods15 in every alternate course are connected to the reinforcing rods at 13beyond the edges of the end tile. By this ar rangement, I am enabled toremove the tie of every alternate course, so as to provide an opening topermit entrance to the silo at any point above the point from which thesilage has been removed, or the point to which it has been filled.

It will be noted that, with the exception of the vertically extendingdoor tiles 3 and 4,

. the tiles in all the courses are of similar form.

It will also be noted that the concrete within the recesses 7 formcontinuous reinforced beams and that'the reinforce of each beam isentirely embedded within the body of the beam, being at a differentlevel than the adjacent joint between the courses. This not only gives areinforced beam of maximum cross sectional area and strength; but italso makes it impossible for any water entering the joint from theoutside of the structure to find its way to the reinforce to causerusting and destruction of the latter. In building these structures theconcrete in the re- CQSSBS 7 becomes 111010 01' less S65 before theconcrete beams, and this is effectively accomplished by the constructiondescribed.

A further advantage of the construction consists in the arrangement ofthe vertitically extending tiles adjacent to the door opening. It willbe noted that these tiles are alternately of longer and shorter lengthsin succesive courses so as to break joints and bond these tiles with theadjacent horizontally extending tiles. 'Also that the verticallyextending tiles have recesses into which the reinforcing members extend;and that these reinforcing members can be readily connected by tiesacross the door openings at as many of the courses as may be clesired.The vertically extending side cavities in the tiles adjacent to the dooropening also provide spaces into which the mortar between adjacent tilescan flow and thus form a secure connection between adjacent tiles. Thesedoor tiles are also provided with recessed inner portions which formseats for the doors under the pressure of the contents of the silo.

The advantages of my invention result from the provision of a silohaving reinforcing rods seated in grooves in the upper faces of thetiles.

I claim A silo built of a plurality of superimposed rows of tiles, therebeing a doorway in said silo, the tiles having horizontally extendinggrooves in their upper faces for receiving reinforces, the tiles at thesides of the doorway having vertically disposed openings extendingthrough them and vertically disposed recesses on their inner faces forthe reception of doors, the tiles of the silo between the tiles at thesides of the doorway having horizontally disposed openings therethrough,and a metal reinforce lying within the horizontal grooves in the upperfaces of the tiles, substantially as described.

In testimony whereof, I have hereunto set my hand.
